Be it known t-hat I, WALTER L. FORWARD, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented new and useful Improvements in DeepJWell Pumps, of which Athe following is a specification.

This invention relates to deep well pumps.

The object of this invention is to provide a deep well pump embodying details of construction whereby the cost of manufacture andthe cost of erection of the pump are greatly reduced over other pumps of the same class; to provide means whereby a pump may be erected in wells of small diameter with great facility and of such construction that the diameter of the pump proper can be nearly as large as the diameter of the Well.

It is a particular object of the invention to provide means whereby the several sections of the pump casing may be rigidly, practically and eifectually jointed so as to form a substantial, continuous structure of great rigidity thereby forming a strong support or journal for Athe revolving elements.

The invention consists of the parts and construction and combination of parts as more fully described and claimed, having reference to the accompanying drawings in which- Figure 1 is a side elevation of an ereted pump. Fig. 2 is a detail sectional view of the lower endof the pump. Fig. 3 is va transverse section on the line X-X of Fig. 1.

This pumpcomprises a pumping head or member 2 upon which rests a distance piece in the form of a cylindrical band or spacer 3, against which is abutted a bonnet member 4. Within this pump head is mounted a suitable impeller `5 having impelling blades 6, which when rotated, create a vacuum in the suction chamber 7 and force the fluid being pumped upwardly through an annular passageway 8 formed between the spacer band 3 and an inner wall 9 of the bonnet 4. The impeller 5 is fastened upon a driving shaft 10 which is supported at suitable points in the discharge column of the pump which is formed by a plurality of superposed tubular sections 11.

One of the .distinctive features of my in vention is a means whereby the several column sections 11 are firmly jointed so as to be substantially watertight and rigid; andv alsoa particular point of importance is the means whereby the pump head sections 2, 3 c

and 4t arejointed in such a manner that the pump body andhaving their ends 13l bent at an angle parallel to the converging mem# bers 2 and 4, 'which are provided with slotted lugs 14,: into/Which the threaded ends 13 of the'ro'ds12'may be inserted and clamped therein by nuts or other equivalent locking devices 15. BF this means the 'pumpy head sections 2 3 an '4 may be firmly and elfectually clamped .togetherl and form a sub` stantial bearing for the reveving members ofthepump;

An important advantage "tained bythe use 'of the bent rods ,'12, is t members can be assembledguickly andreliably wit-hout the use of devices projecting beyond the diameter of the ump member,

'at' the pump f i and the entire strength oft e tie rods 12de conserved sinceY by bending their ends 13A toward the center of the pump and thread- 1 ing -them it is not necessary to weaken :by cutting the tie rods 12. As shown inFig. 2,. the bentrods 12 lie close A.up to the outside Wall of the pump proper in such a manner` as to throw the nuts on the ends of the rods into such a position that they will clear the inner wall of the well into which the pump drops and operates, thus taking up a mini-. mum amount of space and making it pos sible to utilize almost the total diameter of the Well for the body of the pump.

The means by which the discharge column sections '11 are jointed comprise collars 16,

provided von their periphery vwithwlugs or flanges 17, erforated as at l18 to .receive tie rods 19.wh1ch extend from collar to collar projecting through the perforations '18 and being provided on their 4ends with lookin nuts 20 so as to draw the collars throug which the rods 19 pass tightly toward one I .105

another. As shown in Fig. 2 these collars are bored, as at 21, to receive the turned dwn ends of the column sections 11, which" l are-adapted to be inserted into the collars y 16, and in order to prevent the leakage of Huid past the inserted ends of the sections 11 the collars are provided with grooves 22 to receive packing rings 23 which are preferably rings of round rubber or other suitable material. These packing grooves 22 are purposely placed about midway the length of the counterbored portion of the collar 16 so that the sections 16 slip Well past the packing ring 23 before striking the' shoulder 24 against which they abut, thus preventing the gasket or ring from getting between the end of the discharge sections and the shoulder 24, which would result, if it should occur, in throwing out of alinernent the superposed discharge column. The collars 16 not only form means for receiving and supporting the column sections 11 but each collar is also provided With a central hub portion 26 provided with suitable bearing material in which is supported the driving shaft 10 of the pump. f

It will be seen then that by this form 'of structure the pump head members2, 3 and4 are firmly jointed by the bent tie rods 12; and the firstA superposed section 11 of the discharge column is clamped to the pump head by a plurality of tie rods 19; and that all of Athe remaining super-posed sections ,11 are each firmly jointed by successive supporting collars 16 and their respective tie rods 19; and that the discharge elbow is .also connected to the pump discharge column with similar tie rods 19. A

By the joint between the several sections 11 afforded by my particular design I obviate the necessity of threading the ends of the sections and the collars 16, thus saving in manufacturing cost and further saving in cost of erection at the place of operation of the pump, land' obtaining by the use of these several tiel rods 19 a more substantial structure than Iwould be obtained if the sections l1 were scnewed to their respective collars .16.

Having thus described my invention, what I claimand desire to secure by Letters Patent, is* l A deep Well pump comprising a pump head casing, a rot-ary piston mounted in said pump head casing, a vertical shaft for driving said rotary piston,tubular sections ex-` tending upwardly from said pump head casing, spider collars between each of said tubular sections, said spider collars being counter-bored to receive the ends of said tubular' sections and to forma seat for the same, spiders extending inwardly from said collars, bearings for said shaft carried by said spiders in 'substantially axial alinement with the laxis of 'said tubular sections, the exterior of' said collars being provided with -apertured iextensions, and supporting tension rods adapted to form the entire support for said pump head.

In testimony whereof I have hereunto set my `hand in the presence of two subscribing witnesses. f
